PNEUMATIC STRAW -STACKER.

SPECIFICATION forming part of Letters Patent No. 720,486, dated February10, 1903.

Application filed June 21,1902.

To all whom, it may concern:

Be it known that we, WILLIAM C. BOBBY and WILLIAM N. RUMELY, citizens ofthe United States, residing in Laporte, in the county of Laporte andState of Indiana, have invented a new and useful Improvement inPneumatic Straw-Stackers, of which the following is a specification.

This invention relates to improvements in wind-stackers. Our endeavortherein has been to simplify the apparatus and also to render it moreconvenient in use.

The invention consists in the novel construction of parts and devicesand the novel combinations of parts and devices hereinafter described.

The details of our invention are fully shown in the accompanyingdrawings and described below herein.

In the drawings, Figure 1 is a side elevation of a thresher providedwith our invention. Fig. 2 is a longitudinal vertical section. Figs. 3and 4c are sections on the lines 3 3 and 4 4, respectively, of 'Fig. 2.Fig. 5 is a bottom plan of the fan and stacker-tube.

In said drawings, 6 6 represent portions of I the thresher-casing; 7 7,the thresher-frame;

8, the shaker; 9, a straw-deflecting rack at the rear end of the shaker,and 10 the sieve. The straw-collecting chamber consists of 'an upperstationary part having side walls 11,- rear wall 12, and aclosed top 13,and a lower part made in the form of a hopper and consisting of a hopperportion 14, a rear plate 15, and sides 16. Thetop 13 may be hinged, asat 17, and the rear wall may be hinged, as at 18. The hopper is adjustably supported, as hereinafter set forth, and to permit its changesin position without forming openings between it and the stationary partof the chamber which would destroy or lessen the power which thestacker-fan exerts in the chamber the sides 16 of the hopper areextended above the bottom of the sides 11 and also to the rear wall 12andmove in the open space formed between the sides 11 and sheetmetallinings 19, as plainly shown at Figs. 2, 3, and 4. For the same purposethe plate 15 Serial No. 112,610. (No model.)

is extended above the bottom of the rear wall I close the opening at thefront of the hopper by means of two overlapping plates 21 and 22,

onehinged to the hopper and the other hinged to a stationary part of thethresheras, for instance, the inclined cross-board 28. A depending plate24, having slots for lockingscrews, is employed to adjust theinclination of the upper plate, and the free edge of the lower platerests on inclines 25. attached to the under face of board 23. With thisconstruction it will be seen that the continuity of the joints betweenthe stationary and movable parts of the collecting-chamber will not beaffected by the tipping adjustments permitted the movable part, theslides 16 then merely moving through the space prepared for them in thesides of the stationary part, while the plate 15 moves vertically andalways in close bearing with wall 12, and the plate 21slides on plate22.

The stacker-fan is shown at 26, its casing at 27, and the stacker-tubeat 28. The fancasing effects a close joint with the bottom of the hopper14, the delivery-opening in the latter being-coincident with the openingin the top of the casing, so that the straw may be drawn into the fanfrom the hopper. Both the casing and the entire movable portion of thecollecting-chamber are supported upon a U-shaped'frame 29. (Best shownat Fig. 4.) The limbs of this frame extend far enough upward to permittheir attachment to the sides 16, and they are pivoted upon coincidentpivots and 31, bolted to the adjacent uprights 7 of the machine. Thismanner of supporting the fan-casing and movable part of thecollecting-chamberpermits both to be tipped with the frame 29 wheneverit is desired to vary the inclination of the stackertube, this being thetipping adjustment already mentioned. The fan is supported upon a block32, secured upon the central part of frame 29, which is widened for thepurpose of giving a broad support, and the fan is actuated by a shortshaft 33, passing down through the block and carrying a bevel-gear 34 atits lower end. The gear 34 meshes with a pinion 35 on a shaft 36,revolving in bearings 37 and 38, attached to frame 29, and said shaftcarries a pulley 47, driven by belt 39 from pulley 40, which is in turndriven by belt 41 from any convenient source of power. Pulley 40 may besupported on pivot 30, if desired. This construction of fan-drivingmechanism is unaffected by the changes in position of the fan and itscasing occurring in the tipping adjustments while the fan is inoperation. The adjustments are effected by means of a hand-lever 42 oncross-shaft 43, carrying crank -arms 44, connected to the lower portionsof the limbs of frame 29 by connecting-rods 45. The lever has aspringpawl engaging a curved notched bar 46, so that it can be locked inany one of a number of positions,,and thus retain the adjustment as longas desired. The fan-casing is attached to the sloping annular surface ofblock 32, its bottom being cut out to fit said annular surface, and asthe block turns freely around the axis 33 and acts as a turn-table thecasing and stacker-tube are permitted to swivel, so that the tube can bedirected to either side of the machine desired without any stoppage inthe operation of the machine. The supporting-frame is provided with aseries of flanged rollers 48, located as shown in Fig. 5, the flanges ofthe rollers setting over the edge of the block and preventing anyvertical movement by it and also confining it against horizontalmovement.

It will be noticed that the pivots of the frame 29 are located in theplane of the top of the fan-casing. e regard this as important, asthereby only a small amount of movement or throw is imparted in thetipping adjustments.

We claim- 1. The combination in pneumatic strawstacking apparatus, of astraw collecting chamber having a tipping adjustable lower portion, afan drawing its air with the straw from said chamber and located undersaid lower portion and tipping therewith, and a stacker-tube projectingfrom the fan-casing, substantially as specified.

2. The combination in pneumatic strawstacking apparatus, of a strawcollecting chamber having its bottom made in hopper form and adapted totip, a fan drawing its air and the straw from the tipping-chamberbottom, a swinging frame supporting both the chamber-bottom and the fan,and a stackertube supported from the fan-casing, substantially asspecified.

3. The combination in pneumatic strawstacking apparatus, of a strawcollecting chamber having a tipping adjustable lower portion, a fanunder said lower portion and tipping therewith, and a stacker-tubeprojecting from the fan-casing, the latter being swiveled on its axis toallow changes in the direction of the tube, substantially as specified.

4. In pneumatic straw-stacking apparatus, the combination of the fan,the fan-casing and the stacker-tube, the casing having a swivelingadjustment about the fan-axis and also having a tipping adjustment, andthe tube being carried by the casing, substantially as specified.

5. In pneumatic straw-stacking apparatus, a stacker-tube mounted upon averticallytipping and horizontally-swiveling support, whereby thedirection of the blast can be changed as needed without stopping thethresher and without the employment of flexible joints in the tube,substantially as specified.

6. The combination with the tipping strawcollecting hopper and the fandrawing the straw from the hopper, of a U-shaped pivoted framesupporting both the hopper and the fan, and means for locking the framein its adjusted position, substantially as specified.

7. The straw-collecting chamberhaving an adjustable tipping lowerportion, and means for preserving the continuity of the joints betweenthe stationary and adjustable parts of the chamber notwithstanding thechanges in position of the adjustable portion, substantially asspecified.

8. The straw-collecting chamber having an adjustable tipping lowerportion, and means for preserving the continuity of the joints be tweenthe stationary and adjustable parts of the chamber notwithstanding thechanges in position of the adjustable portion, consisting of overlappingplates or devices, substantially as specified.

9. In a pneumatic stacker, a tipping fan and a supporting-frametherefor, the latter being pivoted on a line with the top of thefan-casing, substantially as specified.
